SAW Wire

AUTOTHERME GRADE-T

AWS: SFA 5.23 ENi1

EN ISO CODE: 14171-B SUN2

Copper coated solid wire for submerged arc welding. These wires are suitable for welding of similar composition where impact properties required at sub zero temperature down to -60 degree Celsius.

Autotherme Grade- T low alloy solid wire is suitable for welding of similar grade steels. The weld metal possesses high tensile strength, and meets the radiographic quality requirements. Especially suitable for welding of matching composition in power plants, Refineries, Petrochemicals and Fertilizer Plants. Suitable for welding of ASTM steels: Grade ASTM A516Gr.60,65,70 & A537 Class 1 or2 etc.
